Black Vine Weevil Control

An unchecked problem

Black vine weevil larva can seriously damage hop root systems - setting off a cascade of negative consequences. Damaged roots reduce nutrient uptake which limits plant growth and vine vigor. The resulting hop plant is water stressed, vulnerable to disease, and less productive - diminishing yield and profit.

Left untreated, black vine weevil pressure will intensify each year, leading to the premature decline of your yards.

We can help.

Multi-year root protection

At Persistent BioControl, we produce insect attacking nematodes that kill black vine weevil larva before they can damage your hops.

Our nematodes are microscopic worms that live in the soil. Just one application will protect your field for multiple growing seasons, lowering black vine weevil pressure and protecting valuable yield.

Our product can be applied through any center pivot or spray rig - no special equipment required. And you can apply anytime the soil temperature is above 50F.

An Affordable, Long-Term Solution

Pricing starts at $200 / acre for our Black Vine Weevil formula. Discounts are available for large orders.

Since our nematodes are persistent, this is one-time expense that will pay dividends for years to come.

Learn more about pricing.

Application is Simple.

For fields with center pivot irrigation, our nematodes can be injected straight into the irrigation water.

Alternately, any ground spray rig can be used for application. To prepare the sprayer, flush the tank and all lines, then remove all screens and filters.
